I haven't been around as long as some, but I think I've been around
longer than Robert, and I can say that I don't recall serious
performance patches, particularly ones around lock management and which
change a fair bit of good, generally being white-listed from feature
freeze or being pushed in after beta1.
Perhaps I've missed them or perhaps there's been a few exceptions that
I'm not remembering that make it look routine rather than an exception
basis. We might have tweaked a config variable or changed a #define
somewhere close to the end of a cycle, but I really don't put those into
the same category as this change.
Thanks,
Stephen
